Solar architecture against wrong formulas

Again and again, there are critics which want to proof it's uneconomically

Ideal weight: Flying dwarf computation
So try a little bit with the weight example before You go to the next lesson. It is necessary to rip down all wrong computation methods before You learn about solar architecture

Insulation material thickness optimum
Who brings a computation method to all architects which hides the price for the heating equipment, in order to sell more expensive heating equipment and less insulation material?

Thermal insulation
Are in the formula from the last page somewhere the costs for the heating system? This shows that the formula is wrong.
